AUTOMATIC CLOCK-WINDING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 427,381, dated May 61890.

Serial No. 328,356- (No model.)

To aZZ whom it may concern:

Be it known that I, OTTO URBAN, of Nagy Kikinda, in Austria-Hungary,have invented a new and useful Self-Acting lVindin g Device for Clocks(pendules,) of which the following is a specification, reference beinghad therein to the accompanying drawings.

My object is to provide a winding mechananism which will becomeautomatically inop- IO erative when the spring or weight is completelywound, and also to utilize the movement of a door in opening and closingas the motive power.

In the drawings, Figure l is a side elevation of the winding mechanismwith the parts in position for the winding operation, the weight beingonly partially wound up. Fig. 2 is a similar View with the weightentirely wound up and the partsin inoperative condition, this viewshowing also the connection to the door. Fig. 3 is a plan View 011 linea 03 of Fig. 2. Fig. 4 is a detail view of the actuating device at thedoor. Fig. 5 shows the operating-pawl detached.

The winding-arbor o is of ordinary construction and is connected with amotive spring (not shown) in the usual manner, or with the weight g bymeans of the cord r and sheave *r. ()n this arbor is fixed rigidly aratchet 7b, which is engaged by an operating-pawl f,

pressed into contact with the teeth thereof by spring f. This pawl withits spring is carried by a rocking disk 0, loosely journaled on thearbor. The operating-cord s is connected 3 5 with the rocking plate atc, and when pulled upon will partially rotate said plate, which actionwill be transmitted to the arbor through the pawl and ratchet f h, thuseffecting the winding of the spring or cord 0" with its attached weight.After each action and before the winding is completed the rocking diskis returned to normal position by means of the weight p,which is conneeted thereto by means of lever Z, pivoted at Z, and cord p, passingover a sheave 2'. This weight applies a tension to the cord 13, whichthus effects the retraction of the rocking disk for a new action. If,however, the effect of the weight 1) is removed from the cord p',therocking plate will not be retracted, and subsequent movement of theoperative cord will be without effect upon the winding mechanism. Thisresult is desired when the winding is completed and is secured by meansof the lever Z, which has a portion 772 in the path of the pulley r, sothat just before the weight has been wound up su [liciently and duringthe final winding action the said pulley will strike the portion 071,raise the lever and weight 13, and thus relieve the retracting-cord p oftension, preventing the immediate return of the rocking plate for a newoperation. This action is illustrated in Fig. 2, the cord p being slack,unaifect'ed by the weight, and the rocking plate remaining in its movedposition. The movement of the operating-cord s is limited, as willhereinafter be seen, and as long as the rocking plate remains in thisposition the parts will not be affected by subsequent pulls upon thesame. The pawl f is pivoted with an arm e 011 the front side of therocking plate, which arm is acted upon by a lever (Z, pivoted on theplate. As the mechanism runs down, the rocking disk moves around withthe ratchet, because the pawl remains in engagement therewith, Fig. 2,and the disk thus gradually returns to normal position, and the purposeof the lever (Z and arm 6 is to arrest the disk when it reaches normalposition by disengaging the pawl from the ratchet, which is effected bythe lever (Z striking a pin 0L, after which the works may continue torun down without moving the rocking disk,which is now in position foranother action. i

The rope s is actuated by the opening and 8 3 closing of a door in thefollowing manner: It is connected with a rope Z) by a turn-buckle s, foradjustment, which rope passes around sheave u and is connected to alever b 011 a rock-shaft a, held in bearings just above the door. Thisshaft has also a bent arm formed with two inclined surfaces a a As thedoor is opened and closed, it bears upon these surfaces and thus raisesthe arm, rocks the-shaft, and pulls upon the operating-rope to turn therocking disk. It will be obvious that when the disk is at the extremelimit of its movement, as in Fig. 2, the operating-rope will then beslack and subsequent movements of the door will not affect the partsuntil they return toward normal position.

I claim as my invention- 1. In combination, the Winding-arbor, theratchet thereon, the pawl, the disk carrying the same, theoperating-rope s,extending from the disk in one direction, theretracting-rope 1), extending from the disk in the opposite directionand having connection with the Weight 19, the motor-Weight q, and thelever Z in the path of the weight to be operated thereby, the said leverZ being arranged to lift the retracting-weight P when the mechanism iswound, substantially as described.

2. In combination, the winding-arbor, the ratchet thereon, the pawl, thedisk carrying \Vitnesscs:
